#! /usr/bin/env bash

# Test repository.
#
# Usage: update [options] <dir>
#
# First, the script determines the list of repositories/sections. If <dir>
# contains the repositories.manifest file, then it is the only repository to
# be tested. Otherwise, every first-level subdirectory of <dir> that doesn't
# start with '.' and contains the repositories.manifest file is to be tested.
#
# Then, it makes sure that every package in every repository can be built
# in a clean configuration.
#
# -n
#    Only test new packages. For this to work, <dir> should be (part of) a
#    git repository. Untracked (and changed) files are considered new.
#
# -e <subdir>
#    Exclude the specified sub-directory. Currently only one directory can
#    be excluded.
#
# -t <toolchain>
#    Specify the build2 toolchain install/stage directory. The script will
#    use <toolchain>/bin/b and <toolchain>/bin/bpkd instead of just b and
#    bpkg.
#
# -c <option>|<module>|<var>
#    Specify additional options, modules, or configuration variables to pass
#    to the bpkg create command. For example:
#
#    -c cxx -c config.cxx.loptions=-L/usr/local/lib
#
